Area forecast discussion 
National Weather Service Peachtree City Georgia 
534 am EDT Sat Aug 30 2008 




Short term /today through Monday/... 
airmass over the County Warning Area still mostly dry...except for better 
moisture over portions of central associated with a weak low 
aloft. With afternoon heating...instability becomes marginal and a 
few thunderstorms are possible. Best chance would again be south 
of Columbus to Macon. Easterly flow increasing on Sunday as 
Gustav moves toward the central Gulf...and Atlantic moisture is 
brought westward into the state. Have raised probability of precipitation a bit over the 
County Warning Area for Sunday. With current forecast track for Gustav...Georgia 
would be on the eastern edge with the outer bands affecting mainly 
the western zones. For Monday...have shaded probability of precipitation with the best 
chances over the west tapering to slight chance east. With a 
general easterly flow...have tweaked maximum temperatures toward the 
cooler numbers on the mav/FWC. 




Long term /Monday night through Friday/... 
Georgia will be between two tropical systems at the beginning of 
the week. Also...high pressure building down the East Coast will 
complicate the forecast more. If dry air pushes into the County Warning Area by 
middle week...we could see maybe Wednesday and Thursday with no 
precipitation...before Hanna does whatever it is going to do. 
However...at this point I will not try to time dry/wet periods in 
the extended with all the variables involved. For now...chance or 
slight chance probability of precipitation each day will do.

Aviation... 
winds should stay out of the east all day with high pressure ridge 
beginning to build in from the north. Winds speed will be in the 5 
to 10 knots range all day as well. There are some areas of patchy fog 
but they should burn off shortly after day break. Will begin to see 
afternoon cumulus develop between 16-18z in the 4000-6000ft range. Some 
isolated rain showers/thunderstorms and rain are expected to develop across the area but 
should see the most development south and east of mcn.
